WRENCH..

SPECIFICATION forming part of Letters Patent No. Im0,;305, dated January17, 1905. Application tiled February Il, 1904. Serial No. 192,053.

.To all whom ift may concern:

Be it known that I, H nNicY H. Eier-irma citil zen of the United States,residing' at Altoona,

county of Blair, and State of Pennsylvania, have invented a certain newand usei'ul lmprovement in Wrenches, oi which the follow ing is aspeciiication.

My invention relates to a new and useful iinprovement in wrenches, andhas for its object to provide a wrench in which the movable jaw may bemoved to any position along the shank and quickly set in place, and themovable jaw is constructed upon one side with a beveled surface, whichbeveled surface is provided with teeth, so that by reversing the jaw thedevice is converted into a pipe-wrench.

With these ends in view this invention consists in the details ofconstruction and combination of elements hereinaii'ter set forth andthen specifically designated by the claim.

In ord er that those skilled in the art to which this inventionappertains may understand how to make and use the same, the constructionand operation will now be described in detail, referringto theaccompanying drawings, forming a part oi' this speciiication, in which-Figure l is a side elevation of my improved wrench; Fig. 2, asideelevation of the wrench, a portion of the same being broken away; Fig.3, a section on the line 3 3 of Fig. 1.

A is the iiXed head of the wrench, which has formed with it the shank B.The rearward end oi' this shank is provided with notches extendinglaterally across the same, as represented at C. The rearward portion oi'the head A is made in the form of a hammer-head D, so that when themovable jaw is removed from the wrench the device could be used as ahammer.

E represents the movable jaw through which the shank B passes, so thatthe movable jaw may slide upon said shank. rlhe rearward portion oi' thejaw E is forked, the prongs E passing' each side of the shank B and aconsiderable distance to the rear thereof.

F is a block which is adapted to slide in between the outer ends of theprongs E', and these prongs E have inturned ends which lit over a iiangeupon the block F. This block F is then secured in place by the pins F,which pass through the prongs and also through the block.

G is a set-screw which is threaded through the block F, as shown inFigs. 2 and 3.

Il is a gib which is adapted to lit between the prongs E and between theshank B and the block F. rlhe face of the gib next to the shankisprovided with teeth to correspond to the notches C in the shank.Suilieient distance is left between the gib H and the block F to allowior the gib being drawn out of engagement with the notched surface C ot'the shank. The inner end of the set-screw G is provided with an annulargroove G', and this inner end fits in to a circular hole formed in thegib. Pins l pass through the gib upon each side of the setscrew throughthe annular groove (Jr, so that said set-screw is swiveled in the gib,as shown in Fig. 2. Thus as the set-screw is threaded through the blockF when said set-screw is turned in one direction or the other the gib iseither raised out of contact with the shank or forced into contacttherewith. Upon each end oi2 the gib are Yformed rearwardly-extendingflanges H, which pass upward upon each side ot' the block F and serve toguide the gib in its movement. One side oi" the movable jaw E isstraight and smooth, and this side is turned toward the iixed jaw and isopposed to the same when the device is used as a monkey-wrench. Theother side of the jaw forward of the shank is beveled, and this beveledsurface is provided with teeth Ff, and as the handle B, formed with theshank, is no larger than the shank the movable jaw F. may be slid fromoif the handle and placed upon the shank again in a reversed position,so that the teeth E2 will be opposed to the lixed jaw, and the devicecan then be used as a pipewrench.

The advantage of my improved wrench is that by one turn oi the screw Gthe movable jaw is reversed so as to be slid at any point along theshank, and then by turning the screw back this jaw is tixed securely inplace, and therefore the wrench can be adjusted quickly to any size nutand will have a greater range of movement than an ordinary monkeywrench,and by Vforming the movable jaw as shown a pipe and monkey-wrenchare-com- IOO bined in one, and by removing the movable jaw entirely thedevice can be used as a hammer, and l accomplish this by anextremelysimple construction, and yet the wrench Iis exceedingly durableand is not liable to get out of order.

Of course I do not wish to be limited to the exact construction hereshown, as slight modications could be made without departing' from thespirit of my invention.

Having thus fully described my invention, what 1 claim as new and usefulis# In a wrench, a fixed head, a shank formed with said fixed head, ahandle formed with the shank no larger in cross-section than said shank,a movable head through which the shank extends, the rearward side of theshank being' provided with a series of notches, the rearward portion ofthe movable head being fork shape, an inwardly extending flange formedat the outer end of each of the prongs of the forli, a block rabbetedupon the sides so as to fit underneath said flanges and be flush withthe upper surface of the same, said block adapted to be slid in betweenthe prongs endwise, pins passing through the prongs and through saidblock, a gib interposed between the block and the notched surface oftheshank, teeth formed upon the in- 'ner face of the gib adapted to engagethe notches, a screw threaded through the block and swiveled in the gibfor raising and lowering said gib, means for guiding said gib in itsmovements independent of the screw, the forward end of the jaw of themovable head being formed iiat on one side and beveled on the other, thebeveled surface being provided with teeth so that when the head isreversed the wrench can be used as a pipe-wrench, as and for the purposespecified.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing witnesses.
